Application led March 4, 1903. Serial No. 146,046.

To all 'whom 'it may concern:

Be it known that I, MITCHELL F. MCCAR- THY, a citizen of the United States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Im rovements in Carbureters, of which the ollowing is a specification.

This invention relates -to apparatus for the production of gas, and has particular reference to`oil-gas machines, of the carbureting type, and is designed to provide a system of chambers or reservoirs, connections and apemployment with a carburizing tank or chamber of a volatile-liquid supply tank communicating therewith, an air-treating tank for preliminarily treating the air before admitting it to the carbuiizing tank, and an air storage chamber` My invention further consists in novel means for controlling and directing the flow of air to and through the carburizing tank, and means for utilizing the original source of airsuplply to insure ow ofthe volatile liquid from t e supply to the carburizing tank.

My invention further consists in various details of construction and combinations of parts as hereinafter described and particuarly pointed out in the claim.

The invention will be more readily understood by reference to the accompanying drawings, forming a part of this specification, and in which,

Figure 1 is a partly sectional elevation of an apparatus em odying my invention. Fig. 2 is a similar view of an apparatus provided with a modification of the air-pipe arrangement and a heating jacket for the carburizing chamber. Fi 3 is a bottom plan of one ofthe series of ba elates. Fi 4 is a similar view of the other orm of ba e-plate.

Referring now to the drawings in detail, numeral 2 refers to the preliminary, air-treating tank, 3 to the carbureting tank proper, 4 to the li uid supply tank, 5 to a novel form of gage t erein, 6 to the filler-opening, and

7 to a ressure-re ulating air pipe, referabl providled with a sitable valve 8, arlid leadiny to said supply-tank 4 from the origina source of compressed air. The treatin(i tank 2 is provided with a liquid-supply inlet 10 and the air-supply pi e 11 entering the tank preferably throufr the stuffing-box 12 and terminating near t e bottom of the tank. The air-outlet 13 communicates with the pipe 14, preferably having a suitable valve 15, which pipe 14, in one construction, communicates with the lower part of the carburating chamber through the interposition of a pi e 16, and in the other construction `di rect y.

The baiie-plates comprise a series of two sets of differently-formed, alternately-disposed disks 17 (Fig. 3) and 18 (Fig. 4), which will be hereinafter more fully described. A final gas-outlet pipe 19 leads from the top of the carbureting tank 3, and an oil-supplyr pipe 20 leads thereto from the oil-supply tank 4. The pi e 20 is preferably provi ed with a valve 21 y means of which the flow therethrough may be regulated. The original source of air sup ly is from the compressed-air storage tan 24, from which leads the main air-supply pipe 23, preferably valved at 22 to control the supply.

In Fig. 2 I have shown the carbureting tank 3 provided with a steam or hot-water jacket 25, supplied from any suitable source through the pipe 26, 27 referring to the outlet pipe. Any suitable source of hot water, vapor or steam supply and manner of circulation may be provi ed and the detalls thereof are immaterial so far as this invention is concerned.

I have referred to the tank 2 as an airtreating tank. f I have discovered that air may be with good results prepared in many ways for the process of carburizing. This tank may contain water, through which the air is forced to remove small particles of solid matter, or it may contain an acid, such as sulfuric, which on account of its affinity for water will take up all moisture in the air, leaving the latter pure and dry and in better condition to absorb an hydro-carbonaceous vapor. Or the tank 2 may contain heavy oil drained from the main carbureter anddeposited therein, thus partially carbureting the. air in advance of its admission to the main carbureting chamber 3 which contains fresh oil. The contents of this tank 2, therefore, may vary with the character of the volatile liquid employed in the carbonizing chamber and the nature of the final product desired.

The tank'4, while apparently small in vertical section may represent a long, low tank of considerable larger' capacityv than the car- Yburetingvessel 3, although, of course, its dimensions may be of any scope desired. The chief functions of this supplytank are to provide a vessel in which the oil level may be noted and regulated and a convenient part for refilling. The service of the gage-glass 5 is the reverse of that of thef ordinary steam l'gage-glass employed with engine boilers, in

thatthe gage is read from Within. It is therefore made of somewhat larger diameter and held in a metal body 5 closed normally by a plu 5. By providing the gage within the vesse all dangers which might otherwise arise from breaking of the glass are avoided, the glass being completely incased .within the tank by the plug 5 on the gage-body 5 When ythe oil level is to be noted, the plug is temporarily removed. As a further precaution, the valve 21 may be closed, in casethe lass should be broken, as also the valve 8, if

esired.- This temporarykclosing would not materially aect the comparative oil levels in the tanks 3 and 4.

The pipe- 7 to the tank 4 communicating directly with the source vof compressed air supply, and the gas-pressure in the tank 3 bemg controlled indirectly, vthrough the tankl 2 and its connections, from the same source, and a substantially e ual pressure bein obviously necessary 1n t e two tanks 3 an 4 4, I have shown a pressure-equalizing or regulatv in valve 28, designed to insure a substantia y uniform pressure in the tank 4 irres ective of the. pressure in the compresse air' reducing t e vo ume of residual by-products.

.baffle-plate therein.

The operation of my invention 1s as follows: The -several tanks or vessels having been lled with the proper liquids, substantially as shown in the figures, the valve 22 is opened admitting air into the lower portion of the tank 2, which air rises through theliquid in saidI tank, becomes suitably treated therein, and passes out through the pipe 14-- the valve 15 being openand is conveyed to the bottom of the tank 3 or below the lower The treatedv air will first strike the imperforate or solid portion 18 of the plate 18 and be deflected thereunder to the apertures 18". 'Passing through the apor solid ortion 17, of the plater17 neXt above. eflected underneath the portion 17 the air encounters the downwardly-pro j ecting ridge or flange 17 is deilecteddownwardly thereby and is finally allowed to escape through the central aperture 17 of the plate 17 to encounter, upon rising, another solid portion 18 of a plate 18, and so 'on, the plates,l as previously stated, being arranged in alternate order. Each of these deflections or obstructions tends to break up the air bubbles formed, so that by the time the air issues into the upper or gas-storage portion of the chamber 3 it is thoroughly carbonized and united with the atoms of oil into a uniform gas compound. The pipe '19, or final outlet for the gas, is designed to be suitably connected with the distributing pipes provided with the usual stop-cocks.

During the above operation, the valve 21 will be normally open, ermitting the flow of oil from the tank 4 to t e carbureting vessel,

ythe air-supply pipe 7 providing the necessary pressure to overcome the ressure'of the as in the chamber 3. In t e absence of t pi e, the oil would have to be pumped or ot erwise forced into the carbureter, as isthe common practice. It is obvious that the pressure of the vcarburized. air in the upper portion of the tank or vessel 3 will be, consid? erably less than the original pressure'in the pipe 11 and at the mouth thereof, owing to i the resistance of the liquids which'has been overcome; hence greater pressure must -be provided through the pipe 11 than through the pi e 7, for which pur ose I prefer to provide the valve 28, although the ressures may be equalized by means of the va ves 8 and 22. The compressed-air storage tank 24 may I be of any desired size, form and location, and any common or usual means for compressing f the air therein may be employed, so far as my invention is concerned. I ave found it .a material advantage `to provide the steam or hot-water jacket 25, as stated, particularly where steam or-hotwa`ter facilities make its employment possible or convenient. The arrangement of the pipe 14 within or without the tank 3 is immaterial, and in either case 'the arrangement of the plates 17 and 18 is the same, 'no change being required in these plates other than the perforation of the plate 1.8 at its center to rovide for the pipe 14, making the connectlon water tight, and making the aperture 17 in the plate 17 substanf tially larger than the diameter of the pipe 14. Many modifications of the minor details of my improved gas-prodilcing ap aratus will doubtless readily suggest themse ves to those skilled in the art to which it appertains, and I therefore do not desire to limit my invention to the specific construction and arrangements of parts herein shown and described.

, Having thus described my invention, I claim as new and desire to secure by Letters Patent- A gas produc'in apparatus comprising a carbureting cham er adapted to contain a supply of liquid hydrocarbon, 'a heating jacket around said carbureting chamber, a preliminary air treating chamber adapted to contain a supply of air treating fluid, a connection'between the up er portion of the air treating chamber and tllie carburetino' chamber, a hydrocarbon reservoir, a normally open valved connection between the h drocarbon reservolr and the carburetmg c amber, an

air storage chamber, la pipe leading from the v air storage to the treating chamber, the outlet end of said pipe being below the level of the liquid contained therein, aA branch from said ipe to the hydrocarbon reservoir above the evel of the iuid therein, and means whereby air will be sup lied to the hydrocarbon reservoir under ower pressure than to the air treating chamber.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
